I mean, casting with tarrot cards and crystal balls for bards and undead patron are pretty on themes for the speculated, yet to be announced, positively-presented Vistani centric november book!
This seems both highly likely based on available evidence and like a suicide mission to me.
"Steer a course straight through the Eye of Attempted Positive Fantasy-Romani Stereotypes!"
"But cap'n, no crew has ever survived that, and dozens have attempted it"
"I SAID STEER A COURSE, YER LILY-LIVERED SWABBY!"
(Their ship was never seen again)
The only way I see this not ending somewhere on the rocks of "But it's a positive dehumanizing stereotype! A positive one I tell you!" (as screamed by whoever wrote WoD:Gypsies when they dragged him away), is if they revert to the 4E take on the Vistani, where they're a trans-dimensional nomadic wagon-train made of all races, who are all Vistani, because it's a thing you become, by choice.
I am excited for a thousand Pop-Culture-Hamlet Bards who are at this very moment, preparing "hilarious" D&D-themed takes on the Yorick speech (or rather, a small part of it) given the "skull" option, though.
I love the randomized effect thing though, that's cool.
The Warlock Grave-Touched thing is either decent or totally broken depending on how you read it. It kind of sounds like if you're using your Form of Dread, you potentially turn your EB into Necrotic damage and then, what, roll another d10 for damage on every single attack?
I think maybe what they're trying to say is that you get the extra damage on the one attack where you use the FoD Frighten, but that is not what they wrote.
